IMPROVEMENT IN WATER-SUPPLY REGULATORS.

Specification foming part of Letters Patent No. 153,000, dated July 14,1874; application led February 5, 1874.

T 0 all whom lit may concern:

Be it known that l, JosEPE KELLY, of Brooklyn, Kings county, New York,have invented an Improved Tater-Supply Regulator, of which the followingis a specification:

Figure l is a perspective view of my irnproved apparatus. Fig. 2 is aperspective vieuT of a modiiied form of the same. Fig. 3 represents myimproved apparatus applied to a furnace.

The object of this invention is to furnish an improved apparatus forregulat-ing the supply of Water automatically to the vapor orevaporating-pan of furnaces, lheaters, &c., directly from thestreet-mains, so that it will require no supervision and no tank.

The invention consists in the combination of the pivoted lever providedat one end Wit-l1 an evaporating-pan, at the other end with anadjustable Weight, and at its 'pivoting-point with a graduated arm, anda connecting-rod for operating the stop-cock of a water-pipe, with afurnace or heater, and ivith a Waterpipe and its stop-cock, ashereinafter fully described.

A is the cvaporating-pan, which is placed in the heater or furnace, andwhich may be of any desired size, according to the amount of evaporationrequired. The pan A is supported by a lever, B, the end of which isforked to receive said pan, which is pivoted to said forks, so that thesaid pan may be kept level while the lever B Works upon its pivot C.'The end pa-rt of the lever B, with which the pan A is connected, isjointed to the body of said lever, and may hang downward, as shown inFig. l, project upward, as shown in Fig. 2, or be'extended in line withthe body of the lever, as shown in Fig. 3. lVhen projecting upward thehinged part of the lever B should be provided with a guide to keep itnearly, perpendicular. The pivot O of the lever is attached to abracket, which is secured to the ceiling or to some other support,insuch a position that the pan A may be in the hot-air chamber o f thefurnace or heater. From the outer end of the lever B is suspended aWeight, D, which maybe moved nearer to or farther from the pivot C,according as less or more Water is required in the pan A. E representsthe Water-pipe, which is brought into such al position that it maydischarge the Water directly into the pan A. The flow of water from thepipe is regulated and controlled by a stopcock, F, in the usual Way.With the handle of the stop-cock F is connected the end of a rod, G, theother end of which is connected with an arm formed upon the middle partof the lever B, onwith the outer end of said lever, according as therelative position of the various parts of the apparatus may render mostconvenient, and at the same time allow the valve F to be placed at sucha distance from the furnace or heater a-s to be unaected by the heat.The arm formed upon the lever B at its pivoting-point should be providedwith a number of holes for the attachment of the rod G, to enable thesaid rod to be so adj usted that the movement of the lever B will openand close the stop-cock F.

To adjust the apparatus for use, open the stop-cock F and allow theWater to flow until the pan A is as full as desired; the Weight l) isthen adjusted to exactly balance the water and pan; the rod G is thenconnected with the handle of the stop-cock F, and the adjustment iscompleted.

lith this arrangement, as the Water evap` orates, the pan A becomeslighter than the Weight D, and gradually rises, until the movement ofthe lever B opens the stop cock F, and admits another supply of Water,until the pan A again sinks to its former position, which shuts thestopcock F, stopping the in-y flow of the Water, and so on andcontinuously, as long as vaporation continues.

It will be observed that, with this construc tion, as the Waterevaporates, and the pan A` rises, it and the Weight approach the pivotC, so that the vertical line through the center of gravity tends towarda parallelism with the length of the lever B. The result of this is,that more water is required to flow into the pan, before it begins todescend, than enough to bring the lever B to a level, the friction ofthe stop-cock and the various bearings have the same tendency, so thatwhen the panAbegins to descend, it goes down with a prompt and positivemovement.

Having thus described my invention, what I elzmini as new, and desire tosecure by Letor heater, and with a water-pipe and its stopters 1eteut,iscock, substantially as herein shown :md de- The combination of thepivoied lever B, scribed.
